Abstract

Anomalously large Pt195 NMR linewidths have been observed in platinum particles with diameters ranging from 33 to 200. Spin-echo measurements revealed the presence of nuclear spin-exchange diffusion in large magnetic field gradients attributable to the large indirect exchange interaction in platinum. These data indicate that there are electron spin-density oscillations near the platinum surface consistent with a simple model ascribing free-electron behavior to the s-like conduction electrons.
